God causes some things to happen that some would consider bad, yeah. He ordered the genocide of wicked nations (men, women, livestock, and yes, even children). Same God on both sides of the bible. He took the lives of Ananias and Sapphira. He consumed Nadab and Abihu with fire. He rained fire on Sodom and Gomorrah. He deludes the reprobates of 2 Thessalonians 2. He gives those in Romans 1 over to their sin. He gave Satan permission to afflict Job and kill his family. He allowed the afflictions Paul and the torture and murder of the fist century church. He allowed the thorn in Paul's flesh.
He disciplines us as well. That can come in the form of physical ailments, catastrophes, a prick on our conscience, and the like.
We also make decisions that lead to things like this because we are sinful people.
It is no surprise to him however, when someone commits a sinful act. He wasn't surprised by Hitler and what he did. He wasn't surprised by the millions of abortions in America. He isn't surprised by a fatal car accident due to a drunk driver. All of these things were already known to him before he created anything. He created everything anyway and said let it be so.
God doesn't just let these things happen without a purpose though. We know from scripture that all things work together for the good of those who love him, who are called according to his purpose. Again, look at Joseph and his brothers. Joseph says "what you intended for evil, God intended for good", therefore, we see man's fallen will being exercised for evil, but God's sovereign will being exercised right along with it, the very same act, for good. The crucifixion itself. The sinful murderous desire of those who crucified Jesus was them exercising their fallen will, but it was also Gods will for the greatest act of mercy by him ever known to mankind. The very same act, evil will of man alongside the good will of God.
I dunno how to be any more clear in my stance on this, so I hope this suffices.
